The news today is full of concern about lithium batteries, airlines are worried passengers items might cause an in-flight fire. Well yes lithium batteries do burn rather vigorously, but then they are the same batteries that are in the pilots tablets that are now used instead of flight manuals, and indeed the plane has large lithium back up batteries for the flight instruments (and remember there's been quite a few fires caused by the planes batteries) so maybe passengers should be more worried than the airlines?
The fact remains that lithium batteries are highly inflammable, yet curiously ni-cad batteries (nickel/cadmium) battries which worked nearly as well as lithium were banned because they were toxic, but then at least they didn't burst into flame!
